Greptile Summary

Adds a consolidated dashboard overview for services, backups, domains, and deployments.

• Introduces overview API endpoints and shared sorting/icon helpers.
• Adds filtering, sorting, pagination, navigation, and service/domain actions.
• Reuses the existing deployment tables and backup restore dialogs.
• Redirects deployment navigation to the new overview tab.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the previously reported compose redeployment guidance issue is fixed by displaying the shared redeploy notice whenever the toggle mutation reports that redeployment is required.

@narcisonunez I think we should remove deployments side item, and move in to a tab in this new route overview
